Generously coat a large sauté pan with olive oil and toss in 5 of the smashed garlic cloves and 2 of the broken chilies. Bring the pan to high heat — it should be screaming hot!

Toast or grill the bread, then rub each slice with the whole garlic clove, drizzle with olive oil, and keep in a warm spot.

As the garlic starts to just slightly turn brown, toss in half the shrimp and season with salt. Stir and cook for 1 minute, or until shrimp just turn pink. Remove from heat, and immediately stir in half the lemon juice and half the parsley. Transfer the shrimp to a dish and keep warm. Repeat this entire process with the remaining ingredients.

Divide the arugula among 4 serving bowls, top with shrimp, and drizzle with the cooking juices. Cut each slice of toast in half on the bias and tuck the bread into the side of the bowl. Serve immediately.
